can instantiate instances of your new product. 
So if not clients do the installation, I would not be able to 
instantiate objects?

AFAIK: At minimum, you need one client to do the installation once.
After that, you can turn it off forever on all clients
(until you install more products).

Yes, and the new product will not show up under Control_Panel/Products, 
that's my understanding. Should be easy to test, though.

Okay, but what does installed mean?
Would it actually stop new instances of object classes provided by the 
product being instantiated, or would it just prevent help pages and 
other conflict-error-on-startup-y things from happening?

cheers,

From what I understand it prevents the installation/writing of a 
product into the ZODB (the products management part of the 
Control_Panel) and thus prevents conflict errors. If the product is 
already installed (e.g. by a client who is allowed to do so) then you 
can instantiate instances of your new product. The setting does not 
prevent that.
